IMPROVEMENT IN OUTSIDE FLUES AND DAMPERS FOR HEATlNG-STOVES.

Specification forming part of Letters Patent No. 44, I 80, d atcd September 13, 1864.

To aZZ whom it may concern:

Be it known that I, HENRY Gr. GILES, of the city of Troy, in the county of Rensselaer and State of New York, have invented a new and useful improvement in what is known as base-burning stoves, and others which have 110 outer revertible flue; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

Figure 1 shows a vertical section of a baseburning stove with improvements attached. Fig. 2 shows the division of an oblong flue by an end view with the double-acting damper.

Fig. 3 shows an inner view with said damper closed. Fig. 4 shows an end view with the damper closed. Fig. 5 shows a T-pipe with suspended flue division. same suspended flue division turned.

The same letters indicate like parts in all the-figures.

My invention consists, chiefly, in an outward revertible flue, J and L, constructed by placing the division K in the center of the back 'pipe, at the top of which is a damper, Q,

which, when turned back, opens a direct upward draft from the chamber H, but when turned forward turns the draft from chamber H down the flue J, to the lower end of division K, and thence up the flue L to the pipe which leads off to the chimney. At the lower end of the flues J and L is a damper, It, through which, when open, air from near the floor is admitted and taken up into the flue L and passed off through the pipe into the chimney. Thus, by taking cold and impure air from the room this damper It becomes a complete ventilator to the room where the stove is in use, and at the same time performs another officeviz., by this large admission of air for ventilation, the draft through the flue J is impeded and moderately checked. The damper M, when turned up, opens a communication from ash-chamber M to flue L, which causes a powerful backdraft that prevents all dust and ashes from escaping into the room when shaking the grate or taking up the ashes. It also acts as a counteraction of the combustion of the fuel in chamber A by diverting the supply of oxygen.

The flues J and L may be constructed in many diflerent ways. They may be made Fig. 6 shows the,

longer or shorter. They may be constructed in a round, oblong, oval, or square pipe. One or both of these flues may be brought down inside the outer casing of the stove, or they may be projected partly or wholly outside the fect the same thingviz., the changing the draft from revertible to direct, and from direct to revertible. Fig. 2 shows a double-acting damper, W, at the top of the flues J and L, turned so as to open both flues for adirect upward draft, with the wing V extended perpendicularly crosswise of the oblong pipe, while the other wing, X, is horizontally at right angle from the flues J and -L. Fig. 3 shows said damper W closed with wing V, shuttin the flue L from chamber H, while Fig. 4 shows wing X closing flue J at the top, but leaving it open to the chamber H. Fig. 5 shows a vertical section of around perpendicular pipe connected at the top with a horizontal pipe,which leads from the top part of any stove, to which it may be attached at the end Y. In the center of the pipe I) is suspended the partition K, which turns the draft from the stove down the flue J, and thence up the flue L to the exit-pipe Z. Fig. 6 shows the suspended partition K turned lengthwise of pipe Y and Z, leaving the said pipe open from Y to Z, thus making a direct draft from the stove to which it maybe attached.

The effect of the exterior revertible flues as to retaining the heat in the stove is the same as an interior vreverting flue. The flue J becomes a balancing column against that of the heat in chamber H arising from the combustion, the surplus of which is taken off by the flue L.

I claim- 1.
